C3D-260619-R2 · Redline 2 - fix Tract A bearing quadrants error

Corrects the three reversed Tract "A" bearing labels (north S89-59-36E -> N89-59-40W, east S12-52-11W -> N12-52-08E, south N10-39-27E -> S10-39-20W). Values computed from the surveyed geometry. Edits the text inside the anonymous annotation block definitions.

C# payload

// REDLINE #2 - Tract "A" bearing quadrants are reversed.
// Verified against the actual SS-HERO TRACT A geometry (azimuths computed from the surveyed
// endpoints, not assumed):
//     north line 210.00'  label S89d59'36"E  ->  computed N89d59'40"W
//     east  line 220.00'  label S12d52'11"W  ->  computed N12d52'08"E
//     south line 210.00'  label N10d39'27"E  ->  computed S10d39'20"W
// The labels were written for the opposite direction of travel. The redline calls for
// North -> N_W, East -> N_E, South -> S_W, which matches the computed values.
//
// The labels are anonymous BlockReferences (*U200..*U207) created when the parcel labels were
// exploded, so the text lives inside each block DEFINITION. This edits the DBText/MText inside
// those definitions - every reference updates.
// ADDS NOTHING, erases nothing. Host owns Tx; host regens after commit.
